What does everyone think about those AST buffs?

Is this the case? The way I read it is that healing any other party member gave the Synastry'd person 40% heal. Does it in fact give the tank the bonus as well if you heal the tank?

Yes it is. Meaning you can choose to use a 573 potency shield on cd. Roughly ~critlo with 0 rng.
